Question about 2002 Ford SVT Focus

1 Answer

Strange idle, A/C click, stumble (7 second intervals)

Regardless whether or not my 2002 SVT focus is idling or accelerating, every 7 seconds on the dot a clicking noise happens that sounds just like the air compressor clicking on and off very quickly. Right as this happens my tach jumps anywhere from 100-200rpms, and if I'm driving, the car accelerates strangely for a split second and returns back to normal. Then seven seconds later, it happens again. Help!

That is indeed your A/C compressor kicking on and off. Your a/c is driven off of the engines crankshaft and uses power from your engine to run the system.

It's possible that you have a slightly loose belt that causes the engine to hesitate a bit when the compressor turns on and off.

Engine idles up to 2500 and after 5 or 7 seconds, goes back down to 1200 rpm 2002 escort SOHC


Clean out the throttle body carefully and replace the auxilliary air idle valve. There is a resetting process for this valve so dont just fit and hope!
Check on Google or forums but i think ...when fitted you turn on ignition but dont start car , then put the accelerator pedal slowly to fully open, hold it for a min then release. start and drive car until warm and the recheck.
If the idle is high then settles it is not an air leak. It is something stuck that then releases which is only throttle flap or idle valve. It is always a goid idea to replace fuel, oil, air filters on normal service intervals.

Rough idle and poor fuel consumption


Sorry guys i was late with my feedback... So here it goes.. I have no check engine light.... Currently running the stock tune as well.. The car has no tps, pcv or egr valve.. It is all controlled by the electronic throttle body which i recently cleaned but didnt help with my problem. I ordered a new fuel pump as well, just didnt get the chance to install it yet. Cant change the fuel filter as it is builtin within the pump. However, shouldnt the fuel pump or fuel filter cause engine stalling, bucking and hesitation? I doubted the fuel pump could be causing this since the problem only occurs at idle. By the way, there is no missing on any of the cylinders.

02 ford focus se 2.0 split port,at idle would run rough, & almost sounds like its surging while idling auto zone said fuel to lean finally just quit, & it wouldtry to start but it finally wouldn't...


the MAF (mass air flow) meter may be faulty, this is typical of the symptoms you are getting. It is just after the air filter in the large bore pipe leading to the inlet on the engine, not a cheap part but you may get one on ebay, just remove and unplug the original and swap it.

My tps is at 0.99% is that correct for a 2002 ford focus lx.when at a complete stop as i try to accelerate it revs really high and for a long time before it hits second gear


The tps is actually a rheosat type switch. It essentially sends a reduced voltage (between 0vdc and 5vdc) to the ecm to indicate throttle plate opening. If it is stuck at 0.99% it is not operating properly. There is no internal part fix, only replacement.
